Make the Strawberry Jam:

• In a small saucepan, combine strawberries, sugar, and lemon juice. Cook over medium heat for 5–7 minutes, mashing gently as the berries soften.
• Stir together cornstarch and water to create a slurry, then add to the pan. Cook for 1–2 more minutes until thick and glossy. Let cool completely before using.

  Shortcut: You can also use about ⅓–½ cup of good-quality store-bought strawberry jam if you’re short on time!

Make the Dough:

• In a large mixing bowl, combine the 6 cups of flour, instant yeast, sugar, and salt.
• In a seperate bowl, mix together the whole milk and buttermilk, then heat the mixture until it reaches about 110°F.
• Pour the milk mixture, melted butter, vanilla extract, eggs and egg yolk into the flour mixture. Mix until a soft dough forms.
• Knead the dough by hand on a lightly floured surface or using a stand mixer for 5-10 minutes, until it's smooth and elastic. Gradually add up to 1/2 cup of additional flour as needed. The dough should be slightly tacky but easy to handle.
• Place the dough in a greased bowl, cover, and let it rise in a warm place for about 1-1.5 hours, or until doubled in size.

Prepare the Filling:

• In a medium bowl, beat cream cheese until smooth.
• Add sugar, vanilla, and salt. Beat until fluffy and thick.

Assemble the Rolls:

• Once the dough has risen, punch it down and roll it out on a floured surface into a rectangle (about 18x12 inches).
• Pipe or spoon thick stripes of cheesecake filling across the dough then swirl cooled strawberry jam over the top. Don’t overmix—leave streaks..
• Roll the dough tightly from the long edge, trimming off the ends. Slice the remaining dough into 8 evenly sized rolls.
• Place the rolls in a greased 9x13-inch pan, leaving space between them to rise.
• Cover and let the rolls rise again for about 30-45 minutes.

Bake the Rolls:

• Preheat the oven to 350°F (160°C).
• Pour the heavy cream (1/4 cup) evenly over the rolls before baking.
• Bake the rolls for about 25-35 minutes, or until they are golden brown.

Make the Cream Cheese Icing:

• Beat together the cream cheese and butter until smooth. Add the powdered sugar and vanilla, then add cream to reach a smooth, spreadable consistency.
• Spread the icing over the warm rolls and enjoy!
